TDA1514A integrated circuit is a hi-fi power amplifier for use as a building block in radio, tv and other audio
applications. The high performance of the IC meets the requirements of digital sources (e.g. Compact Disc equipment).
The circuit is totally protected, the two output transistors both having thermal and SOAR protection
